Abstract
The invention discloses polyethylene glycol modified melamine resin, aiming at providing modified melamine resin which has toughness and low water absorption and does not contain nonyl phenol; the technical scheme comprises the following components in parts by weight: 80-120 parts of polyethylene glycol, 50-70 parts of phenol, 180-class melamine, 2-3 parts of p-toluenesulfonic acid, 2.5-3.5 parts of triethanolamine, 4-5 parts of triethylamine, 330-class 430 parts of formaldehyde and 270-class 330 parts of solvent; relates to the technical field of copper-clad plates.
Description
Technical Field
The invention relates to a resin, in particular to polyethylene glycol modified melamine resin, and also relates to a preparation method of the polyethylene glycol modified melamine resin; belongs to the technical field of copper-clad plates.
Background
Polyethylene glycol (PEG) is a high molecular polymer with the chemical formula of HO (CH)2CH2O)nH, no irritation, slightly bitter taste, good water solubility and good compatibility with a plurality of organic components. Has excellent lubricity, moisture retention, dispersibility and bonding agent, can be used as an antistatic agent, a softening agent and the like, and has extremely wide application in the industries of cosmetics, pharmacy, chemical fiber, rubber, plastics, papermaking, paint, electroplating, pesticides, metal processing, food processing and the like.
The molecular structure of the polyethylene glycol is a long flexible carbon chain, and the polyethylene glycol contains a large number of ether bonds to endow the polyethylene glycol with toughness, and in addition, the hydroxyl groups at two ends of the molecule can participate in the reaction with phenol and have good hydrophilicity, so the polyethylene glycol is very suitable for replacing nonyl phenol to be used for toughening and modifying phenolic resin, and is prepared into water-soluble resin for impregnating insulating paper. Meanwhile, compared with nonyl phenol, polyethylene glycol is non-toxic, harmless, non-irritant, environment-friendly and free of adverse effects on human, animal and plant contact.
The polyethylene glycol has different properties according to different relative molecular masses, and from colorless, odorless and sticky liquid to waxy solid, the molecular weight is too small, the toughening effect is insufficient, and the molecular weight is too large, so that the permeability of the resin to paper fibers is influenced.
The european union, "legislation on chemical registration, evaluation, licensing and restrictions" (simply "REACH") has been formally implemented. According to the regulatory requirements, the eu committee will establish a unified chemical monitoring and management system and complete the management of all relevant chemicals 2012 ago. The REACH regulation has a wider influence range than the instructions implemented in the european union in recent years, and it incorporates about 3 ten thousand chemical products and downstream products such as textiles, light industry, and pharmaceuticals in the market of the european union into 3 management and monitoring systems respectively for registration, evaluation, and approval, and products not incorporating the management systems cannot be sold in the market of the european union, and REACH is a regulation for the european union to perform preventive management on all chemicals entering the market thereof.
As a major concern of REACH regulations, the list of highly focused Substance (SVHC) candidates has undergone many updates since REACH was effective. On 19/1/2021, eu chemical administration (ECHA) added 2 substances from the new counseling list to the official SVHC candidate list, by which time the SVHC candidate list had been increased to 211.
If any SVHC candidate substance with the concentration of more than 0.1% is contained in the 'goods' product released into the European Union market, European Union manufacturers or importers should fulfill the obligation of notice, notice and the like specified by the REACH regulation: when the consumer consults, the relevant information is provided to the consumer within 45 days; at levels > 0.1% and total quantities of this material entering the eu of >1 ton/year, eu producers or importers must first notify ECHA product party for market in the eu. If a product (e.g., paint, ink, etc.) of the "substance or mixture" type contains an SVHC candidate, the manufacturer should provide safety specifications (SDS) to downstream users. And from 5/1/2021, the supplier of the goods must report the information of the SVHC substances in the goods in the SCIP database of ECHA according to the requirement of the european union "waste framework directive".
Nonyl phenol is newly added to the eighth SVHC list formally effective 12/19/2012. And nonyl phenol is mainly used for modifying phenolic resin, and the flexibility is provided for the product by virtue of the flexible long chain at the ortho position of the phenolic hydroxyl. Although the amount of nonylphenol added to the whole plate is small, the limit of nonylphenol is occasionally exceeded during actual inspection. This will greatly affect the exit of my board and downstream products. Therefore, while the toughness of the plate is not reduced, the nonyl phenol is necessarily eliminated from the formula

1) adding 80-120 parts of polyethylene glycol 400, 8-12 parts of phenol, 18-22 parts of melamine, 60-80 parts of water and all p-toluenesulfonic acid weighed according to claim 1 into a reaction kettle, stirring, heating to 85-95 ℃, and keeping the temperature for 1.5 hours; then adding 2.5-3.5 parts of triethanolamine and cooling to 75-85 ℃;
2) adding 4-5 parts of triethylamine and 430 parts of 330-containing organic formaldehyde into the step 1), heating the residual phenol, melamine and formaldehyde in the step 1) to 90-100 ℃, keeping the temperature for 20 minutes, then beginning to take 10ml of resin to test the mixing degree of water, stopping heating when the mixing degree reaches 150ml of 100-containing organic formaldehyde, adding the residual solvent to cool, and taking out the mixture from the kettle when the temperature is lower than 60 ℃.
6. The polyethylene glycol modified melamine resin of claim 1, which is used as a first glue for bonding in the production of copper-clad plates.
